Title: Electrolytic peeling method by high-velocity polarity inversion
Inventor: NISHIYAMA TOSHIHIRO
IPC: C25F7/00
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electrolytic peeling method capable of surely and rapidly removing deposits while suppressing the corrosion a material to be treated.  <P>SOLUTION: The method for peeling the disposition film formed on the surface of the material to be treated which is a conductive metallic material comprises using the material to be treated as a cathode, using an electrolyte for generating gas by the electrolysis from the material to be treated, energizing the cathode and anode in an electrolyte cell to generate the gas on the contact surface of the material to be treated and the deposition film and peeling the deposition film by the gas. Polarities are alternately inverted at a high velocity, by which anodic oxidation is prevented and the corrosion of the material to be treated is suppressed; in addition, the formation of the gas is promoted by dropping the reaction products of the cathode sticking to the surface of the material to be treated from the surface.  <P>COPYRIGHT: (C)2003,JPO
